Abstract.

The two-quasiparticle rotational bands in deformed doubly even nuclei in the rare-earth region have been studied in detail. A number of interesting features like odd-even staggering and signature inversion have been observed. The phenomenon of signature inversion/reversal is observed experimentally in 162  66Dy, 170 70Yb and 170  74W in even-even nuclei. Two quasiparticle plus rotor model (TQPRM) calculations are carried out to explain the reverse pattern of signature in 170  74W for the rotational band having configuration \(\{(h_{11/2})_{p} \otimes (d_{5/2})_{p}\}\).
